Use this workshop calculation to turn measured dimensions and the selected construction convention into a cut, spacing, fit, or material-planning value.

Material

Riser board material: plywood, MDF, or solid wood.

Look up the typical riser board thickness for plywood, MDF, and solid wood materials. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Riser board thickness (mm)

Typical riser board thickness in millimeters: 19 for plywood, 16 for MDF, and 19 for solid wood.

• Nominal dimensions, kerf, moisture movement, hardware clearances, wall squareness, and manufacturer instructions can change the required shop dimension. Measure the actual assembly and test critical joints on scrap before cutting finished material.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Complement the calculated dimension with a physical story stick, dry fit, or full-size layout. Follow the hardware, coating, adhesive, or machine manufacturer's limits where they differ from a rule of thumb.

• Domino Size Lookup

  Look up the tenon thickness and length of a Festool Domino size.

• Veneer Matching Yield Lookup

  Look up the typical usable yield percentage for a veneer matching pattern.

• Biscuit Size Lookup

  Look up the width, height, and thickness of a standard biscuit size.
